The resident vehicular portion 42 generally includes: the vehiclenetwork communications bus 37; the ECM (electronic control module) 38;the PCM (power train control module) 40; the ECUs (electronic controlunits) 41; and other engine control/monitor computers andmicrocontrollers 39.

While the system is described as having an on-board portion 30 and aresident vehicular portion 42, it is also understood that the presentinvention could be a complete resident vehicular system or a completeon-board system.

The DTE telemetry microprocessor is interconnected with the OBDinterface 36 for communication with the vehicle network communicationsbus 37. The vehicle network communications bus 37 in turn connects forcommunication with the ECM 38, the engine control/monitor computers andmicrocontrollers 39, the PCM 40, and the ECU 41.

It isfurther understood that the amount and type of vehicle data andinformation will change from manufacturer to manufacturer and evolvewith the introduction of additional vehicular technology.

Continuing now with the DTE telemetry microprocessor 31, it is furtherinterconnected for communication with the DCE wireless telemetrycommunications microprocessor 32. In an embodiment of the invention, anexample of the DCE wireless telemetry communications microprocessor 32is a Leon 100 commercially available from u-blox Corporation. The Leon100 provides mobile communications capability and functionality to thevehicular telemetry hardware system 30 for sending and receiving datato/from a remote site 44. A remote site 44 could be another vehicle or aground based station. The ground-based station may include one or moreservers 19 connected through a computer network 18 (see FIG. 1). Inaddition, the ground-based station may include computer applicationsoftware for data acquisition, analysis, and sending/receiving commandsto/from the vehicular telemetry hardware system 30.

In an embodiment of the invention,an example of the GPS module 33 is a Neo-5 commercially available fromu-blox Corporation. The Neo-5 provides GPS receiver capability andfunctionality to the vehicular telemetry hardware system 30.

The DTE telemetry microprocessor 31 is further interconnected with anexternal non-volatile memory 35. In an embodiment of the invention, anexample of the memory 35 is a 32 MB non-volatile memory storecommercially available from Atmel Corporation. The memory 35 of thepresent invention is used for data logging.

The DTE telemetry microprocessor 31 is further interconnected forcommunication with an accelerometer (34). An accelerometer (34) is adevice that measures the physical acceleration experienced by an object.Single and multi-axis models of accelerometers are available to detectthe magnitude and direction of the acceleration, or g-force, and thedevice may also be used to sense orientation, coordinate acceleration,vibration, shock, and falling.

The transmission may becontrolled and set by the vehicular telemetry hardware system 30 atpre-defined intervals. The transmission may also be triggered as aresult of a significant event such as an accident. The transmission mayfurther be requested by a command sent from the application softwarerunning on the server 19.

Intelligent I/O Expander Hardware System

Referring now to FIG. 3 of the drawings, there is illustrated anintelligent I/O expander generally indicated at 50.

The intelligent I/O expander 50 includes a messaging interface 53 for aconnection to a private bus 55 (in an embodiment of the invention, theprivate bus 55 is a cable connection, or private cable). The private bus55 provides for connection to other intelligent I/O expanders (see FIG.5) as well as the vehicular telemetry hardware system 30 (see FIG. 4).In an embodiment of the invention, the messaging interface 53 andprivate bus 55 is based upon a CAN bus. The messaging interface 53includes five conductors. There are two power conductors (12-24 volts),a ground conductor, a CAN High conductor, and a CAN Low conductor.

Messaging on the private bus 55 is based upon a frame consisting of andID and a varying number of data bytes. The ID portion may be 11 bits or29 bits and the data may be zero to eight bytes of data. Messages may besent over the private bus 55 when the bus is idle. The vehiculartelemetry hardware system 30 and all intelligent I/O expanders 50connected to the private bus 55 see all messages by monitoring theprivate bus 55. A message may be received by either the vehiculartelemetry hardware system 30, or a particular intelligent I/O expander50 based upon the ID contained in the frame. If the ID matches theparticular device, then the device receives the message. The dataportion of a message may contain data, information, or device commands.

In addition, the intelligent I/O expander 50 includes a configurablemulti-device interface 54. The configurable multi-device interface 54provides for connection to a multi-device bus 56 (in an embodiment ofthe invention, the multi-device bus 56 is a Geotab™ intelligentconfiguring cable connection). The multi-device bus 56 in turn providesconnection to an interface 61 of a specific device 60. In an embodimentof the invention, the configurable multi-device interface 54 includesthirteen conductors. There are six conductors for bidirectional serialcommunication that include a data set ready (DSR) conductor, a clear tosend (CTS) conductor, a transmit data conductor (TX), a data terminalready (DTR) conductor, a request to send (RTS) conductor, and a receivedata (RX) conductor. This grouping of conductors is for connecting to afirst type of device, a device that requires serial communication. Thereare also four conductors, AUX1, AUX2, AUX3 and AUX4 for connectingauxiliary devices. This grouping of conductors is for connecting asecond type of device (non-serial communication device). Finally, thereare two ground conductors and one power conductor (12V). The conductorsin association with a Geotab intelligent configuring cable are also usedto establish the type of connection as a serial type or an auxiliariestype and identification of either AUX 1-4, or AUX 5-8. AUX 1-4 and AUX5-8 provide conductors that may be monitored or driven between a highand low state to enable or disable a connected auxiliary. Monitoring ordriving these conductors is dependent upon the particular auxiliarydevice connected to Aux 1-4 and AUX 5-8. Monitoring and driving theseconductors also includes in an embodiment of the invention an autoadjust and resolution feature. For example, when a voltage level isbetween zero and five volts, a number of voltage steps may be associatedwith this range. When a voltage level is between zero and thirty volts,the number of voltage steps is adjusted for resolution for the largerrange of voltages to avoid noise and extraneous data.

The intelligent I/O expander hardware system 50 also includes amicroprocessor 51 and memory 52. Alternatively, the intelligent I/Oexpander hardware system 50 includes a microcontroller 51. Amicrocontroller includes a CPU, RAM, ROM and peripherals. Personsskilled in the art appreciate the term processor contemplates either amicroprocessor and memory or a microcontroller in all embodiments of thedisclosed hardware (vehicle telemetry hardware system 30, intelligentI/O expander hardware system 50, Bluetooth module 45 and Bluetoothbeacon 21). The microprocessor 51 is also connected to the messaginginterface 53 and the configurable multi-device interface 54. In anembodiment of the invention, a microcontroller 51 is an LPC1756 32 bitARM Cortec-M3 device with up to 512 KB of program memory and 64 KB SRAM.The LPC1756 also includes four UARTs, two CAN 2.0B channels, a 12 bitanalog to digital converter, and a 10 bit digital to analog converter.In an alternative embodiment, the intelligent I/O expander hardwaresystem 50 may include text to speech hardware and associated firmware(not illustrated) for audio output of a message to an operator of avehicle 11.

The microprocessor 51, CAN 2.0B controller, and firmware computerprogram stored in the program memory communicate with the messaginginterface 53. The messaging interface 53 and private bus 55 may bemonitored by the Can 2.0B controller to send a message, ignore a sentmessage, or receive a message. For example, a message may be received byan intelligent I/O expander 56 when the message ID matches the expanderID.

The intelligent I/O expander 50 may be operated as a serial type in apassive expander mode or as an auxiliaries type in an active expandermode based upon an established configuration of the device.

Passive Expander Mode

A message received by the intelligent I/O expander 50 over the privatebus 55 is converted or reformatted and sent from the intelligent I/Oexpander 50 to a first type of device connected to the configurablemulti-device interface 54. This is accomplished by the microprocessor 51and firmware computer program. This is a protocol conversion from theformat and structure of the message on the private bus 55 to therequirements of a specific device connected by the multi-device bus 56.

Alternatively, a message received by the intelligent I/O expander 50from a first type of device connected to the configurable multi-deviceinterface 54 is converted or reformatted by the microprocessor 51 andfirmware computer program, provided to the messaging interface 53, andsent over the private bus 55. This is a protocol conversion from theformat and structure of the message for the requirements of the specificdevice 60 to the format and structure required by the private bus 55.

In the passive expander mode, the data portion of the message is passedthrough the intelligent I/O expander 50. The data could be passedthrough from the messaging interface 53 to the configurable multi-deviceinterface 54, or from the configurable multi-device interface 54 to themessaging interface 53. The intelligent I/O expander 50 does not haveany logic or control over a device 60, it performs a protocol conversionbetween interfaces. An example protocol conversion is from a CAN bus(private bus 55) to a serial bus (multi-device bus 56).

Active Expander Mode

In addition to the passive expander mode for the first type of deviceand serial communication with the intelligent I/O expander 50, there isalso an active expander mode for a second type of device (auxiliariestype) and non-serial communication. The microprocessor 51 and firmwarecomputer program monitor the configurable multi-device interface 54 andauxiliaries connected to the configurable multi-device interface 54.Data and information may be buffered in memory 52. The intelligent I/Oexpander 50 has logic and monitoring capability over the device 60(auxiliaries). The intelligent I/O expander 50 also has logic andcapability to communicate or signal a high or low state (on or offfunction) to enable or disable the associated device 60 (auxiliaries).When certain monitoring characteristics are met, the data andinformation may be formatted into a frame and a message containing thedata may be sent over the private bus 55 to the vehicular telemetryhardware system 30. Alternatively, the frame and message may be sent toanother intelligent I/O expander 50.

Devices

A number of difference specific devices 60 may be interfaced to theintelligent I/O expander 50. The configurable multi-device interface 54may accommodate a number of different devices 62 and interfaces 61through the configurable multi-device interface 54 and multi-device bus56. When a specific device 60 is connected to the intelligent I/Oexpander 50, messages, data, or signals may be communicated between thedevice 62 and the intelligent I/O expander 50.

For example, if the specific device 60 is a Garmin™ type of GPS device62 with the fleet management interface (FMI15 or FMI 45), the interface61 to the Garmin device may be connected to the configurablemulti-device interface 54 for communication with the intelligent I/Oexpander 50. In this case, the configurable multi-device interface hasone end and configuration to the configurable multi-device interface 54and a second end and configuration to the interface 61, in this example,a Garmin interface. A Geotab intelligent configuring cable provides amapping of conductors between the interfaces.

The DTE telemetry microprocessor 31 and firmware computer program of thevehicular telemetry hardware system 30 includes the logic, commands, andprotocol instructions for communicating with a Garmin device 62 fordetecting the presence of the device. Otherwise, messages received bythe vehicular telemetry hardware system 30 for a Garmin device are senton the private bus 55 to an intelligent I/O expander that in turnconverts or reformats the message and sends it to the Garmin device. TheGarmin device is an example where the vehicular telemetry hardwaresystem 30 is in a passive control mode. Aside from very basic logic,commands, and protocol instructions, the firmware does not have a fulland complete set of logic and commands for the device. In this case, thefull and complete set of logic and commands for the device resides inthe MyGeotab application software on the server 19. Initialization ofthe intelligent I/O expander 50 and the vehicular telemetry hardwaresystem 30 associate the intelligent I/O expander with the passiveexpander mode and the vehicular telemetry hardware system 30 with thepassive control mode and device type.

As another example, if the specific device 60 is an Iridium™ type ofsatellite communications device 62, the interface to the Iridium device62 may also be interfaced to the configurable multi-device interface 54by the multi-device bus 56 for communication with the intelligent I/Oexpander 50. In an embodiment of the invention, an Iridium 9602SBD maybe connected to the intelligent I/O expander 50. The Iridium 9602SBD isa short burst data modem, or transceiver module designed formachine-to-machine solutions for sending and receiving packets of data.The interface includes a serial data interface, DC power input, networkavailable output, and power on/off control line. In this case, theGeotab configurable multi-device cable 56 has one end and configurationto the configurable multi-device interface 54 and a second end andconfiguration to the interface 61, in this example, an Iridiuminterface.

The DTE telemetry microprocessor 31 and firmware computer program of thevehicular telemetry hardware system 30 includes the logic, commands, andprotocol instructions for communicating with the Iridium device in orderto send and receive messages (data and information) as well as controlof the device. Example non-limiting commands include acquiring thesatellite, authenticating the transceiver, sending messages, receivingmessages, exchanging status information, and performing modem control.The firmware has a full and complete set of logic and commands for thedevice. This is an example where the vehicular telemetry hardware system30 is in an active control mode. Initialization of the intelligent I/Oexpander and the vehicular telemetry hardware system 30 associate theintelligent I/O expander 50 with the passive expander mode and thevehicular telemetry hardware system 30 with the active control mode anddevice type.

Both the Garmin and Iridium devices are examples of a first type ofdevice that requires serial communication for sending and receivingmessages and device data. The server 19 and MyGeotab application programcontain the logic and instructions for operating with a Garmin device.The DTE telemetry microprocessor 31 and firmware computer program of thevehicular telemetry hardware system 30 contain the logic andinstructions for operating with the Iridium device. For example, theMyGeotab application program may create and send a command to a Garmindevice. In this example, the message (including the command in the data)is provided to the vehicular telemetry hardware system 30 that convertsor reformats the message to the private bus 55. An intelligent I/Oexpander 50 receives the message, converts or reformats the message tothe multi-device bus where the Garmin device receives the command. Asanother example, the vehicular telemetry hardware system 30 may createand send a command to an Iridium device. In this example, a message(including the command in the data) is provided to the private bus 55.An intelligent I/O expander 50 receives the message, converts orreformats the message to the multi-device bus 56 where the Iridiumdevice receives the command. Persons skilled in the art appreciate thata Bluetooth device may be connected and operated in a passive modesimilar to the example description of a Garmin device, or that aBluetooth device may be connected and operated in an active mode similarto the example description of an Iridium device.

As another example, the device 62 could be a series of temperaturesensors that include an interface 61 and connected to the configurablemulti-device interface 54 by another multi-device bus 56. This is anexample of a second type of device, or non-serial communication devicewherein the intelligent I/O expander 50 monitors the second type ofdevice. The microprocessor 51 and firmware computer program of theintelligent I/O expander 50 contain the logic and instructions formonitoring and logging data with the auxiliaries. The server 19 andMyGeotab application program contain the logic and instructions forinterpreting the logged data from the auxiliaries. The MyGeotabapplication program also contains an identification and mapping of eachauxiliary device interfaced to the configurable multi-device interface54 (Aux 1-4, Aux 5-8).

Persons skilled in the art will appreciate the invention may alsoinclude many other specific devices 60 for connection to theconfigurable multi-device interface 54. For example, Geotab specificdevices, 3^(rd) party devices, additional vehicular sensors, smartphones, computers, analog I/O, digital I/O, driver identification, WiFi,900 Mhz Aerocomm, and Bluetooth devices, Bluetooth modules 45 orBluetooth beacons 21.

Referring now to FIG. 4, an embodiment of the invention is furtherdescribed. In this embodiment, the vehicular telemetry hardware system30 includes a messaging interface 53. The messaging interface 53 isconnected to the DTE telemetry microprocessor 31. In addition, amessaging interface 53 in an intelligent I/O expander 50 may beconnected by the private bus 55. The private bus 55 permits messages tobe sent and received between the vehicular telemetry hardware system 30and the intelligent I/O expander, or a plurality of I/O expanders (seeFIG. 5).

Referring now to FIG. 6, an alternate embodiment of the invention isdescribed. In this embodiment, the vehicular telemetry hardware system30 is connected to the intelligent I/O expander through a gateway 80 onthe vehicle connection 43. The vehicle connection 43 is a CAN busproviding communication between the vehicular telemetry hardware system30 and the resident vehicular portion 42. The gateway 80 passes messagesfrom the resident vehicular portion 42 to the vehicular telemetryhardware system 30, but does not allow messages from the vehiculartelemetry hardware system 30 to be sent to the resident vehicularportion 42. However, the DTE telemetry microprocessor 31 is connected tothe interface 36, the vehicle connection 43 and the gateway 80. Thegateway monitors the vehicle connection 43 and permits messages to besent from the DTE telemetry microprocessor 31 to the intelligent I/Oexpander over the private bus 55. In addition, the intelligent I/Oexpander may send messages over the private bus 55 to the gateway 80 andthe gateway may pass the messages to the DTE telemetry microprocessor 31by the vehicle connection 43 and the interface 36. The gateway 80 willnot allow messages to be sent from the intelligent I/O expander 50 tothe vehicle network communication bus 37 over the vehicle connection 43.

Referring now to FIG. 5, multiple intelligent I/O expanders may beconnected in a sequence and structure to each other. The private bus 55is common to all intelligent I/O expanders and the vehicular telemetryhardware system 30. In addition, the vehicular telemetry hardware system30 and each intelligent I/O expander 50 have the messaging interface 53.This permits a daisy chain like connection between the components forsending and receiving messages over the private bus 55. In an embodimentof the invention, up to eight intelligent I/O expanders may be connectedto a vehicular telemetry hardware system. In another embodiment of theinvention, up to two of the intelligent I/O expanders may be auxiliaries(AUX 1-4 and AUX 5-8). Optionally, the last intelligent I/O expander inthe series may include a terminator connected to the last messaginginterface 53 for noise suppression.

The telemetry wireless beacon apparatus includes atleast one Bluetooth module 45 or device and at least one Beacon module21 or device. For example, current Bluetooth beacon technology isgenerally available from a number of companies to include Estimate,Gimbal™, Onyx Beacon and stickNFIND. The Beacon module 21 canperiodically broadcast an identification and communicate 130 with aBluetooth module 45 in the form of a message with a unique identifier.The Beacon module 21 may or may not include associated data with thebroadcast. The associated data is dependent upon the application andcapability of a particular beacon module 21.

A first embodiment of the telemetry wireless beacon apparatus isdescribed with reference to FIG. 7A. A beacon module 21 or device isgenerally indicated at 21. In an embodiment of the invention, the beaconmodule 21 includes a microprocessor 132, memory 134 and a Bluetoothradio module 136 with integral antenna. In another embodiment of theinvention, the beacon module 21 may include an accelerometer 138. Inanother embodiment of the invention, the beacon module 21 includessensors 140. In another embodiment of the invention, the beacon module21 includes an accelerometer 138 and sensors 140. The memory 134includes a memory for data and firmware to provide the associated logicto interact with the other components (radio module 136, accelerometer138 and sensors 140) to perform the functionality and messaging of thebeacon module 21. In further embodiments of the beacon module 21, thesensors 140 may include all or one of a temperature sensor, a lightsensor, battery level sensor or a pressure sensor. Persons skilled inthe art will appreciate that other sensors including user-definedsensors may be included with the beacon module 21.

In another embodiment of the invention, a Bluetooth module 45 isintegrated with the intelligent I/O expander 50. An example Bluetoothmodule 45 is a Bluegiga BLE121LR integrated circuit with a connectivityrange of 450 meters. The Bluetooth module 45 includes a microprocessor142, memory 144 and a radio module 146. The memory 144 includes a memoryfor data and firmware to provide the associated logic to interact withthe components (radio module 146 and intelligent I/O expander 50) toperform the functionality and messaging of the Bluetooth module 45. TheBluetooth module 45 or device may comprise a single integrated circuitor a chip set of components. The Bluetooth module 45 furthercommunicates with the microprocessor 51 and messaging interface 53 ofthe intelligent I/O expander 50 for sending and receiving messages anddata.

The beacon module 21 communicates 130 with the Bluetooth module 45 inthe form of a broadcast message and the Bluetooth module 45 receives thebroadcast message when the Bluetooth module is within a pre-definedrange. The beacon module 21 communicates a unique identifier andassociated data to the Bluetooth module. The associated data isdependent upon the type of sensors 140 associated with the beacon module21 and may include accelerometer data, temperature data, illuminationdata, pressure data, battery data or other user-defined sensor data.

Referring now to FIG. 7B, an alternative embodiment of the telemetrywireless beacon apparatus is described. With this embodiment, theBluetooth module is a Bluetooth device external to the intelligent I/Oexpander 50. The Bluetooth device includes an interface 148. Theinterface 148 communicates with the configurable multi-device interface54 of the intelligent I/O expander 50 through the multi-device bus 56.Persons skilled in the art appreciate the external Bluetooth device maybe connected to an intelligent I/O expander 50 in either a passive modeor an active mode depending upon the module and application.

Referring now to FIG. 7C, another alternative embodiment of thetelemetry wireless beacon apparatus is described. With this embodiment,the Bluetooth® module 45 is integral with the vehicular telemetryhardware system 30. The Bluetooth module 45 communicates with the DTETelemetry Microprocessor 31 for sending and receiving messages and data.The Bluetooth module 45 also receives broad cast messages from thebeacon module 21.

In operation of these embodiments (FIGS. 7A, 7B and 7C), at least oneBluetooth beacon is associated with at least one object 22 relating tothe vehicle 11. Non-limiting example objects include equipment,equipment associated with a minimum equipment list, sensitive equipment,sensitive objects 22 in transport by the vehicle 11, drivers of thevehicle 11, personnel around the vehicle 11, or objects 22 around thevehicle 11 Each object 22 associated with a Bluetooth beacon uniqueidentifier and optionally the corresponding data is communicatedwirelessly to the Bluetooth module 45 and stored in the memory 144 oralternatively the memory 52 or memory 35. Eventually, each uniqueidentifier and associated data is communicated to the vehiculartelemetry hardware system 30 through the messaging interface 53 andprivate bus 55 or directly into the memory 35 to form a log of data.Alternatively, the unique identifier may be filtered out to communicateonly associated data of interest to the vehicular telemetry hardwaresystem 30. Alternatively, the associated data may be filtered tocommunicate only associated data that is different from the lastcommunication of the associated data. The vehicular telemetry hardwaresystem 30 creates a log of unique identifiers and corresponding data.This log may include other data and information such as GPS coordinates,engine data and vehicle data such as speed, position and direction. Thelog, including the unique identifiers and/or associated data arecommunicated from the vehicular telemetry hardware system 30 over anetwork 18 to servers 19. After communication of a log of uniqueidentifiers and/or associated data, the vehicular telemetry hardwaresystem 30 initiates and creates a new log and the process to monitor andlog data repeats. Persons skilled in the art appreciate that theembodiments of FIGS. 7A, 7B and 7C with respect to the location of theBluetooth module 45 are generally applicable to the embodiments of FIGS.2, 3, 4, 5, and 6 such that the location of the Bluetooth module 45 maybe with the vehicular telemetry hardware system 30, the intelligent I/oexpander 50 or a device 60.

Telemetry Wireless Beacon Methods

The telemetry wireless beacon monitoring, logging and communicating datamethod is described with reference to FIG. 17. Engine data, vehicleacceleration data and location data is either monitored, provided orreceived and logged by the vehicular telemetry hardware system 30.Engine data is monitored through the interface 36, vehicle accelerationdata is provided by the accelerometer 34 and location data (latitude andlongitude) is provided by the GPS module 33. In an embodiment of theinvention, the Bluetooth module 45 disposed integral with the vehiculartelemetry hardware system 30 provides Bluetooth beacon data. In analternative embodiment of the invention, the Bluetooth module 45disposed integral with or connected with an intelligent I/O expandercommunicates monitored Bluetooth beacon data to the vehicular telemetryhardware system 30.

The engine is monitored through the interface and the vehiculartelemetry hardware system 30 receives engine data. The accelerometerprovides vehicle accelerometer data to the vehicular telemetry hardwaresystem 30. The GPS provides GPS data to the vehicular telemetry hardwaresystem 30. The Bluetooth module 45 also provides Bluetooth beacon 21data to the vehicular telemetry hardware system 30. Persons skilled inthe art appreciate that the monitoring, providing and receipt of datamay be concurrent, sequential parallel or in any non-limiting order. Theengine data, vehicle acceleration data, location data and Bluetoothbeacon 21 data are retained in a log of data (memory 35) by thevehicular telemetry hardware system 30. The vehicular telemetry hardwaresystem 30 may further communicate the log of data to a remote site 44 orremote devices and computers 20. Once the log of data has beencommunicated, the monitoring, receiving, providing and logging processcontinues with the next log of data.

The Bluetooth beacon 21 data includes a unique identifier andcorresponding data. The unique identifier identifies each Bluetoothbeacon 21. The corresponding data includes at least one of beaconaccelerometer data, beacon temperature data, beacon illumination data,beacon pressure data, beacon battery level data and beacon user definedsensor data dependent upon the type of number of components integral orin communication with the Bluetooth beacon 21.

The remote computer preprocessing method is described also withreference to FIG. 17. A remote computer and application software, forexample the MyGeotab software application receives, or has access to,the communicated log of data from the vehicular telemetry hardwaresystem 30. The log of data received from the vehicular telemetryhardware system 30 is in the form of raw data. A first preprocessingstep occurs to translate or convert the data into a more useful form.For example, raw engine data into engine codes; raw vehicleaccelerometer data into G forces, minimal G forces, maximum G forces anda range of G forces; raw beacon temperature data into a low, a high andrange of temperatures; raw beacon illumination data into a low, a high,and absence of light or a range of light; raw beacon pressure data intoa low, a high or a range of pressures; and raw beacon user definedsensor data into a low, a high, an absence or range of information.

A second preprocessing step occurs to associate at least one of thetranslated data such as engine codes; speed; G forces; or maplocation(s) with each unique Bluetooth beacon 21 identifier andcorresponding data such as beacon temperature, beacon illumination,pressure or beacon user defined sensor data. Each Bluetooth beacon 21identifier may be further associated with each object 22.

The preprocessing method concludes by storing the preprocessed log ofdata including the translations or conversions and associations. Thepreprocessing method repeats for each receipt of a log of data from thevehicular telemetry hardware system 30.

The remote computer Bluetooth beacon fleet management method isdescribed with reference to FIG. 18. A remote computer and applicationsoftware, for example the MyGeotab software application receives, or hasaccess to, over a communications network such as the Internet, thepreprocessed log of data. Alternatively, the MyGeotab softwareapplication receives, or has access to the log of data. In an embodimentof the invention, the Bluetooth beacon fleet management method includesa step of identifying and associating objects 22 located or associatedwith a vehicle 11. Alternatively, this step may be included in thepreprocessing method. In addition, the Bluetooth beacon fleet managementmethod has access to thresholds and ranges relating to each Bluetoothbeacon 21 and corresponding object 22. For example, these thresholds andranges may include acceptable conditions and unacceptable conditions inthe area of G forces, map locations (geofencing), temperatures,pressures and user-defined sensor limits.

A first case involves the step of identifying and associating eachobject with a vehicle beyond a threshold condition. Each Bluetoothbeacon 21 will broadcast a message with the unique identification, andoptionally data. The Bluetooth module 45 may receive the broadcastmessage when the module is within a range, for example, of 450 meters.That may introduce erroneous results for objects close to a vehicle butnot necessarily with or associated with a vehicle 11. At least one of aBluetooth signal strength, location information, geofencing informationor relative speed of a vehicle 11 compared to thresholds provide adetermination of each object located with a vehicle 11. The outcome ofthis step is an accurate identification of each object having aBluetooth beacon 21 with each vehicle 11. Objects 22 may be determinedas located with a vehicle 11. This involves identifying a beacon uniqueidentifier disposed with an object and the initial vehicle 11 location.Then, the beacon unique identifier is identified at a second vehicle 11location where the second vehicle location is determined by one of avehicle speed or motion, vehicle distance vehicle location or a geofenceevent. When a beacon unique identifier is determined at the secondvehicle location, an accurate number of objects disposed or associatedwith the vehicle 11 are determined. This method occurs for each beaconunique identifier and associated object 22. In addition, the accuratenumber of objects may be further assessed at a third vehicle location orgeofence to determine if there is a missing object condition when abeacon unique identifier is absent at the third vehicle location orgeofence.

A second case involves the step of identifying and associating damage toan object. G force thresholds can be compared to beacon G force data todetermine if an object has sustained damage, for example when dropped.Temperature thresholds can be compared to beacon temperature data todetermine if an object has sustained damage, for example when too coldor too hot or out of an acceptable temperature range for a period oftime. Light thresholds can be compared with beacon illumination data todetermine if an object has been over exposed or under exposed to light.Pressure thresholds can be compared to beacon pressure data to determineif an object has sustained damage, for example with too much or toolittle pressure. User defined thresholds can also be compared to beaconuser defined sensor data. When the corresponding data exceeds a damagethreshold such as a range, or upper limit or lower limit or combinationof range and limits, or time based limit, then a damaged objectcondition is determined. The method involves accessing the preprocessedtelemetry log of telemetry data to identify a beacon unique identifierand beacon data. Then, comparing the beacon data with the threshold dataand when the beacon data is beyond a damage threshold value or a damagelimit value, indicate the object is damaged. Damage threshold values andlimits include G forces, temperatures, pressures or user defined values.

A third case involves the step of identifying and associating hazardousobjects with a potential dangerous condition. G force thresholds, ortemperature thresholds or light thresholds or pressure thresholds oruser defined thresholds can be compared to the corresponding data. Whenthe corresponding data exceeds a hazardous threshold, a range or upperlimit or lower limit or combination or range and limits, or time basedlimit, a hazardous object condition is determined. The method involvesaccessing the preprocessed telemetry log of telemetry data to identify abeacon unique identifier and beacon data. Then, comparing the beacondata with the threshold data and when the beacon data is beyond ahazardous threshold value or a hazardous limit value, indicate theobject is hazardous. Hazardous threshold values and limits include Gforces, temperatures, pressures or user defined values.

A forth case involves the step of identifying and associating eachobject with a vehicle beyond a threshold condition. Each Bluetoothbeacon 21 will broadcast the unique identification, and optionally data.The Bluetooth module 45, when the module is within a range, for example,of 450 meters may receive the broadcast message. At least one of aBluetooth signal strength, location information, geofencing informationor relative speed of a vehicle compared to thresholds provide adetermination of each object located with a vehicle 11. The outcome ofthis step is an accurate identification of each object having aBluetooth beacon 21 with each vehicle 11 compared to a minimum equipmentor minimum object list. When the corresponding data does not equate to aminimum equipment or minimum object list, a missing item condition isdetermined.

Persons skilled in the art appreciate that the four cases may beexecuted in parallel, a sequence or concurrently. Once a damaged objectcondition, or a hazardous object condition or missing item condition isdetermined, then a course of corrective action is communicated as amessage to a computer 20, a compliance report, a management report or anaudio message to an operator of a vehicle 11 through a text to speechcapable intelligent I/O expander 50.

Intelligent I/O Expansion System Methods

The DTE telemetry microprocessor 31, firmware computer program, andmemory 35 include the instructions, logic, and control to execute theportions of the method that relate to the vehicular telemetry hardwaresystem 30. The microprocessor 51, firmware computer program, and memory52 include the instructions, logic and control to execute the portionsof the method that relate to the intelligent I/O expander 50 as well asthe logic and control to execute portions of the method that relate tothe Bluetooth module 45.

Referring now to FIG. 8, an initialization method of the intelligent I/Oexpander 50 and the vehicular telemetry hardware system 30 is describedwith respect to a first case (serial port type detected). Theinitialization for the intelligent I/O expander 50 is generallyindicated at 90.

The initialization method 90 starts with determining the I/O expanderport type (either serial port type or auxiliaries port type). In anembodiment of the invention, if there is no short between the RX and TXconductors, and there is no short between the CTS and RTS conductors,then the port is determined to be a serial port type. This isaccomplished by the firmware sensing the conductors in the configurablemulti-device interface 54 and checking for shorted conductors. For thiscase, set the port type to serial and set the state or mode to passiveexpander mode. Send a message over the private bus 55 to the vehiculartelemetry hardware system ID with the I/O expander ID and an indicationthat the port type is serial. This message will be received by thevehicular telemetry hardware system 30. This informs the vehiculartelemetry hardware system 30 that an intelligent I/O expander with aparticular ID number is configured as a serial port type in a passiveexpander mode.

The initialization method for the vehicular telemetry hardware system 30is generally indicated at 91. This initialization method 91 receives amessage from the I/O expander 50 over the private bus 55. The messageincludes an I/O expander ID and an indication to the port type, in thisfirst case a serial port type in a passive expander mode. The vehiculartelemetry hardware system 30 sends a message to the I/O expander ID thatwill query the device type connected to the intelligent I/O expander 50.The intelligent I/O expander 50 will convert or reformat the messagereceived on the private bus 55 and pass the message to the device 62over the multi-device bus 56. The device 62 will identify itself andsend back a message to the intelligent I/O expander 50 over themulti-device bus 56. The intelligent I/O expander 50 in turn willconvert or reformat this message and send the message over the privatebus 55. The vehicular telemetry hardware system 30 will receive themessage with the I/O expander ID and the device type.

The query of the device type may occur in a number of different ways.For example, if the vehicular telemetry hardwire system is looking todetermine if a Garmin device 62 is connected to an intelligent I/Oexpander 50, then the message to the intelligent I/O expander 50 isbased upon the Garmin protocol to detect the presence of a Garmindevice. If a Garmin device is connected, then the Garmin device willsend back a message indicating a Garmin device is present. If a Garmindevice is not present, there will not be any message sent back and atime out will occur. Assuming a Garmin device is detected, and then thevehicular telemetry hardware system 30 is set to a passive control mode.The Garmin device is an example of a passive control device and personsskilled in the art will appreciate that other types of devices may alsobe included in the passive control mode. A Garmin like query andresponse may also occur for the case of a Bluetooth module 45 connectedto an intelligent I/O expander 50 interface in a passive control mode.

As another example, if the vehicular telemetry hardware system islooking to determine if an Iridium device 62 is connected to anintelligent I/O expander 40, then the message is based upon the Iridiummodem protocol to detect the present of an Iridium device. If an Iridiumdevice is connected, the Iridium device will send back a messageindicating an Iridium device is present. If an Iridium device is notpresent, there will not be any message sent back and a time out willoccur. Assuming an Iridium device is detected, and then the vehiculartelemetry hardware system 30 is set to an active control mode. TheIridium device is an example of an active control device and personsskilled in the art will appreciate that other types of devices may alsobe included in the active control mode. An Iridium like query andresponse may also occur for the case of a Bluetooth module 45 connectedto an intelligent I/O expander 50 interface in an active control mode.

The method for the vehicular telemetry hardware system 30 continuesthrough a list of potential serial devices until the list has beencompleted. The vehicular telemetry hardware system 30 may alsoperiodically check for additional intelligent I/O expanders 50 to ensureexpanders later added are identified and configured.

In addition, while the vehicular telemetry hardware system firmware maycontain the necessary instructions, logic and protocol for devices likeGarmin, Iridium and Bluetooth, additional instructions, logic, andprotocols may be provided to the firmware, or received by the vehiculartelemetry hardware system 30 in real time by sending from the server 19the associated logic and firmware for storage in the memory 35 of thevehicular telemetry hardware system 30.

Referring now to FIG. 10, the initialization method of the intelligentI/O expander 50 and the vehicular telemetry hardware system 30 isfurther described with respect to a second case. The second caseinitialization for the intelligent I/O expander 50 is generallyindicated at 94.

The initialization method 94 starts with determining the I/O expanderport type (either serial or auxiliaries). In an embodiment of theinvention, if there is a short between the RX and TX conductors, thenaux 1-4 has been detected. In an embodiment of the invention, if thereis a short between the CTS conductor and the RTS conductor, then aux 5-8has been detected. The microprocessor 51 and firmware computer programin the intelligent I/O expander 50 sense the conductors and determine ifthere is a short between conductors. This provides for detecting theconfiguration of the port as either AUX 1-4 or AUX 5-8 to the vehiculartelemetry hardware system ID. For this case, set the port type to aux1-4 or aux 5-8 and set the state or mode to active expander mode. Send amessage over the private bus 55 with the I/O expander ID and indicatethe port type as either aux 1-4 or aux 5-8. This message will bereceived by the vehicular telemetry hardware system 30. This informs thevehicular telemetry hardware system 30 that an intelligent I/O expanderwith a particular ID number is configured as an auxiliaries device andAUX 1-4 or AUX 5-8.

The initialization method for the second case of the vehicular telemetryhardware system 30 is generally indicated at 95. This initializationmethod 95 receives a message from the I/O expander 50 over the privatebus 55. The message includes an I/O expander ID and an indication to theport type as either aux 1-4 or aux 5-8. Since this is recognized as anactive expander mode, the vehicular telemetry hardware system 30 sends amessage to the I/O expander ID that includes monitoring characteristicsfor the intelligent I/O expander 50.

The intelligent I/O expander 50 receives the message from the vehiculartelemetry hardware system 30 over the private bus 55 and starts theauxiliaries initialization generally indicated at 96. The messageincludes the I/O expander ID and the specific monitoring characteristicsfor the intelligent I/O expander 50. The intelligent I/O expander 50then sets the monitoring characteristics for the auxiliaries connectedto the configurable multi-device interface 54. Monitoringcharacteristics are not limited to but may include thresholds andchanges in values.

The vehicular telemetry hardware system 30 and each intelligent I/Oexpander 50 connected to the system complete the initialization methodspreviously described with reference to Figure and FIG. 10 to determinewhat devices are connected to what intelligent I/O expanders 50, to setthe I/O expander mode (passive or active), and to set the vehiculartelemetry hardware system mode (active control or passive control), andto associate IDs in the system.

In an embodiment of the invention, there is a cabling technique forconnecting each device 62 and interface 61 to the configurablemulti-device interface 54. For the case with serial devices, theconductors required for serial communication at the configurablemulti-device interface 54 are mapped by a Geotab intelligent configuringcable and provided to the interface 61. This may vary from specificdevice 60 to specific device 60. This also provides an interfacingcapability, for example between and intelligent I/O expander 50 and aGarmin device, or an intelligent I/O expander 50 and an Iridium device,or an intelligent I/O expander 50 and a Bluetooth device.

In addition, the cabling technique also identifies the port type ofserial or auxiliaries (AUX 1-4, AUX 5-8). For example, if the Geotabintelligent configuring cable internally shorts the RX and TX conductorsof the serial interface conductors, then AUX 1-4 is established on theAUX conductors. As another example, if the Geotab intelligentconfiguring cable internally shorts the CTS and RTS conductors of theserial interface conductors, then an AUX 5-8 is established on the AUXconductors. Persons skilled in the art will appreciate that othertechniques may be applied to identify the port type of serial orauxiliaries (AUX 1-4 and AUX 5-8).

The method and operation of the intelligent I/O expander 50 for the caseof a serial port type is now described with reference to FIG. 9.Communication to a device attached to an intelligent I/O expander 50 isgenerally indicated at 92. Communication may either begin at a remotesite or device (server 19) where a message is sent to the vehiculartelemetry hardware system 30 that in turn is received by the vehiculartelemetry hardware system 30. Alternatively, a message may be generatedby the vehicular telemetry hardware system 30. The vehicular telemetryhardware system 30 may send a message to an intelligent I/O expander 50with an I/O expander ID and message on the private bus 55 through themessaging interface 53. The intelligent I/O expander 50 receives themessage (ID's match) from the messaging interface 53 including the I/Oexpander ID and message. The intelligent I/O expander converts orreformats the message for the device associated with the configurablemulti-device interface 54 and sends the message to the multi-deviceinterface 54. A specific device 60 (for example Garmin or Iridium)receives the message through the interface 61.

Communication from a specific device 60 connected to an intelligent I/Oexpander 50 is generally indicated at 93. Communication may also beginwith the specific device 60. A specific device 60 may send a message tothe intelligent I/O expander 50 on the multi-device bus 56 and to theconfigurable multi device interface 54. The intelligent I/O expander 50will receive and convert or reformat the message for the messaginginterface 53. The intelligent I/O expander 50 will send the I/O expanderID and message through the messaging interface 53 to the private bus 55.The vehicular telemetry hardware system 30 receives the message from themessaging interface 53 with the I/O expander ID and message. Thevehicular telemetry hardware system 30 may either log the data from thereceived message, or it may communicate the received message or data toa remote site (server 19) for further processing.

When the microprocessor 51 and firmware computer program convert orreformat messages, it may take several messages and reformatting of themessages. For example, in an embodiment of the invention, messagesreceived over the private bus 55 have a data limitation of up to eightbytes. It may take several messages over the private bus 55 in order toreceive the required data for sending to a specific device 60. In thiscase, messages received over the private bus 55 may be buffered inmemory 52. Then, the data buffered in memory 52 may be reformatted tocreate a message for sending over the multi-device bus 56.Alternatively, messages received over the multi-device bus 56 may bebuffered in memory 52 and subsequently reformatted to create a message,or multiple messages for sending over the private bus 55. The firmwarecomputer program contains the instructions and logic for converting andreformatting messages between the two busses. Alternatively, severalmessages containing partial information may be sent directly if systemspeed permits sending partial information sequentially.

Operation for the case of an auxiliaries port type is now described withreference to FIG. 11. Communicating with an intelligent I/O expander 50is generally indicated at 97. Communication may either begin at a remotesite (server 19) where a message is sent to the vehicular telemetryhardware system 30, which in turn is received by the vehicular telemetryhardware system 30, or a message may be generated by the vehiculartelemetry hardware system 30. The vehicular telemetry hardware system 30may send a message to an I/O expander with an I/O expander ID andmessage on the messaging interface 53. The intelligent I/O expander willreceive the message (ID's match) and set or modify monitoringcharacteristics for the associated auxiliaries. If there are twointelligent I/O expanders 50 configured as auxiliaries, one expanderwould be AUX 1-4 and the other would be AUX 5-8.

Communication from the intelligent I/O expander 50 is generallyindicated at 98. The intelligent I/O expander 50 monitors theauxiliaries through the configurable multi-device interface 54 basedupon the monitoring characteristics. When changes are detected, or abovea threshold, or below a threshold, the data is recorded in memory 52 ofthe intelligent I/O expander 50. The recorded data may be analog data,digital data, or both analog and digital data. The intelligent I/Oexpander may formulate a message and send the I/O expander ID andmessage to the messaging interface 53. The vehicular telemetry hardwaresystem 30 receives the message (ID's match) over the messaging interface53 and logs the data contained in the message into memory 35. Data fromauxiliaries may be logged as analog, digital, or both analog and digitalvalues. The vehicular telemetry hardware system 30 may also communicatethe data to a remote site (server 19).

Operation of the overall system will be explained with an example asillustrated in FIG. 12 where there are three intelligent I/O expandersconnected to the private bus 55 and the vehicular telemetry hardwaresystem 30. The intelligent I/O expanders include a Garmin device 60,(Garmin interface 61 and type of device 62) an Iridium device 70,(Iridium interface 71 and type of device 72), and additional vehiclesensors 75 as AUX 1-4 (77) and AUX interface 76. In addition, there is aGeotab intelligent configuring cable 73 between the multi-deviceinterface 54 (50′) and Garmin interface 61 cable 63, a Geotabintelligent configuring cable between the multi-device interface 54(50″) and Iridium interface 71, and a Geotab intelligent configuringcable 73 between multi-device interface 54 (50′″) and auxiliariesinterface 76. The additional vehicle sensors in this example includedrivers side door (open/close), passengers side door (open/close), andcargo door (open/close) (AUX 1, 2, and 3) (AUX 4 is not used).

Under normal operation, the vehicular telemetry hardware system 30 andDCE wireless telemetry communications microprocessor communicatemessages over the cellular network 17. This is referred to as theprimary path 100.

If the message 111 originates with the vehicular telemetry hardwaresystem 30, the message 111 would be sent over the cellular network 17,or primary path 100 and received by the server 19 as the message 110. Ifthe message 110 originates with the server 19, the message 110 would besent over the cellular network 19, or primary path 100 and received bythe vehicular telemetry hardware system 30 as message 111.

If for some reason the cellular network 17 is unavailable, then thevehicular telemetry hardware system 30 and DTE telemetry microprocessor31 may continue to communicate over the satellite network 13 (assumingand intelligent I/O expander 50 and Iridium like satellitecommunications device). This is referred to as a secondary path 101 and102. In this case, an intelligent I/O expander 50″ is interfaced to thevehicular telemetry hardware system 30 and initialized and configured asa serial type in an passive expander mode and the vehicular telemetryhardware system 30 is initialized in an active control mode with theinstructions and logic for control and operation of the serial device(Iridium device 70).

If the message 111 originates with the vehicular telemetry hardwaresystem 30, the message 111 would be sent over the private bus 55 to anintelligent I/O expander 50″ with the Iridium device 70. The messagewould be converted or reformatted by the intelligent I/O expander 50 andsent to the Iridium device 70 over the multi-device bus 56 and cable 73.The Iridium device 70 would then provide satellite communications 12 andthe server 19 would receive the message as 110.

Additionally, a message 110 could be sent by the server 19 and receivedby the Iridium device 70 and provided to the intelligent I/O expander50″ through the multi-device bus 56 and cable 73. The intelligent I/Oexpander 50″ would send a converted or reformatted message to thevehicular telemetry hardware system 30 over the private bus 55 and themessage would be received as 111.

Referring now to FIG. 13, a further example of an embodiment of theinvention is described. In this example, an intelligent I/O expander 50′is initialized and configured as a serial type in a passive expandermode and the vehicular telemetry hardware system 30 is configured in apassive control mode and may convert or reformat the message between theserver 19 and the intelligent I/O expander 50′.

Starting with a message 121 in the server 19 to be sent to a Garmindevice 60. The message 121 may be provided to the vehicular telemetryhardware system 30 by way of either the primary path 100 or thesecondary path 101, 102 as previously described. The vehicular telemetryhardware system 30 receives the message as 122 and converts or reformatsthe message for sending the message over the private bus 55 to theintelligent I/O expander 50′ identified with the Garmin device 60. Theintelligent I/O expander 50 receives the message over the privateinterface 53 (50′) and converts or reformats the message by themicroprocessor 51 and memory 52. The message is then sent over themulti-device interface 54 (50′), Geotab intelligent configuring cable 56to the Garmin interface 61 where the Garmin device receives the messageat 123.

Additionally, a message 123 could be provided to the server 19. Themessage 123 is provided by the Garmin device 60 to the Garmin interface61, the Geotab intelligent configuring cable 56, and received by theintelligent I/O expander 50 through the multi-device interface 54 (50′).The intelligent I/O expander 50′ converts or reformats the message andprovides the message to the private interface 53 (50′) and the privatebus 55 to the vehicular telemetry hardware system 30. The vehiculartelemetry hardware system 30 converts or reformats the message 122 andprovides the message to the server 19 as 121 by way of the primary path100 or the secondary path 101, 102.

Referring now to FIG. 14, a further example of an embodiment of theinvention is described. In this example, an intelligent I/O expander50′″ is initialized and configured as an auxiliaries type in an activeexpander mode and interfaced by the Geotab™ intelligent configuringcable 78 to the auxiliaries.

In a first embodiment of the invention, the vehicular telemetry hardwaresystem 30 may have the monitoring characteristics for the intelligentI/O expander 50′″ as a message 113. The message 113 is provided by thevehicular telemetry hardware system over the private bus 55 to theprivate interface 53 of the intelligent I/O expander 50′″ as 113. Themicroprocessor 51 and memory 52 of the intelligent I/O expander 50′″establish monitoring of the auxiliaries based upon the monitoringcharacteristics in the message 113.

Additionally, the server 19 may provide the monitoring characteristics.A message 112 is provided to the vehicular telemetry hardware system 30by way of the primary path 100 or the secondary path 101, 102. Thevehicular telemetry hardware system 30 will convert or reformat themessage 112 and provide the message to the intelligent I/O expander 50′″over the private bus 55 and private interface 53 of the expander 50′″.The microprocessor 51 and memory 52 of the intelligent I/O expander 50′″establish monitoring of the auxiliaries based upon the monitoringcharacteristics in the message 112.

Referring now to FIG. 15, a further example of an embodiment of theinvention is described. In this example, an intelligent I/O expander50′″ is initialized and configured as an auxiliaries type in the activemode and interface by the Geotab intelligent configuring cable 78 to theauxiliaries. Furthermore, the intelligent I/O expander 50′″ has receivedthe monitoring characteristics and is monitoring the auxiliaries.

Upon detecting a change or a threshold event, data 114 is captured bythe intelligent I/O expander 50′″ through the cable 78 and multi-deviceinterface 54. The microprocessor 51 and memory 52 of the intelligent I/Oexpander 50′″ create a message 115 containing the data 114. The message115 is provided to the vehicular telemetry hardware system 30 by way ofthe private interface 53 of the intelligent I/O expander 50′″ and theprivate bus 55.

The vehicular telemetry hardware system 30 converts or reformats themessage 116 and logs the data. The vehicular telemetry hardware system30 may further provide the data in a message to the server 19 by way ofthe primary path 100 or the secondary path 101, 102. Applicationsoftware on the server 19 receives the message and associated data 114for further analysis. The application software has an associated log tounderstand what types of auxiliaries are associated with AUX 1-4 as wellas AUX 5-8. For example, AUX 1 is door (open/close), AUX 2 is passengersside door (open/close), and AUX 3 is cargo door (Open/close).
